The Government is appealing to the public to provide houses and land to help solve New Zealand's homeless problem.

It promised today to invest $100m into tackling homelessness, by increasing short-term and long-term housing options and increasing funding for social services.

Rehousing people from the street or temporary housing has been complicated by the lack of available or affordable housing, especially in Auckland.

That led the previous Government to start renting motels to house the homeless. Labour criticised this at the time but admitted today that it needed motels until more homes were available, and has put aside $8m for this purpose.

After announcing the funding today, Housing Minister Phil Twyford pleaded with the public to identify properties that could be used for emergency shelters or pop-up homes.

"We can't do this alone," Twyford said. "If you know of properties that might be available over winter, such as seasonal worker accommodation or private rental homes, we'd like to hear about those.

"We'd also like to identify small land options suitable for temporary housing with power and water connections ready to go, such as marae and private land."

Property owners would be paid market rents, he said; they were not expected to simply donate properties.

"If there's a massive surge over winter, we need to have those other options in our back pocket.

"That's why we are considering relocatable [homes] and small-scale clusters of temporary housing."

Twyford and Prime Minister Jacinda Ardern also appealed to people who were struggling to get into homes to approach Work and Income. There have previously been concerns that homeless people were afraid or unable to get help from WINZ.

Ardern said she wanted a culture change within social services.

"Our call to them, and the instruction we have given, is when it comes to special needs grants, be flexible. Provide for those who are in need. That is what our social services are there for."

Of the $100m Budget funding, $37m was money the Ministry of Social Development had been allocated by the previous National Government but not spent. Every cent would be spent by the Labour-led Government, Twyford said, on finding 1500 short-term emergency housing places, including social housing, motel units, and temporary shelters.

The remaining $63m would go into sustaining and expanding the Housing First programme, which places the most vulnerable homeless directly into permanent houses, rather than temporary shelters, before dealing with any mental health or addiction issues.

National's social housing spokesman Simon O'Connor said the new Government's commitment was a pale imitation of National's.

"[Twyford's] $100 million announcement today is a third of the size of National's package and it's not even all new money," he said.

The Government had limited its options by spending too much on tertiary fees and Shane Jones' regional fund, he said.

In all, National funded about 2200 emergency housing places and 900 Housing First places.

Labour's announcement will fund 1500 emergency housing places and 550 Housing First places, though Ardern said there would be further housing measures in the Budget on May 17.

The number of people waiting for social housing has been rising since mid-2015, and is now about 6200 people.

About 40,000 people are believed to be homeless in New Zealand, which includes not just rough sleepers but people in insecure housing.

Twyford warned today that homelessness was not just an Auckland problem. MSD was observing "acute levels of homelessness" in centres like Tauranga, Hamilton and Wellington, and smaller regional centres like Blenheim.
